Hi Allan,
You're on Linux, so is there a reason why this won't work in a shell:
touch ~/.fonts.conf
vim ~/.fonts.conf
replace vim with your favourite editor, and then paste in the lines
suggested in ?pdf, save and then start R.
For your clients; can't you just email them the file and get them to
save it as ~/.fonts.conf. If they are running Linux themselves they
should be able to manage that. If they are on Windows, this isn't an
issue for them, just for your system; note that it is the rendering on
*your* system that is problematic. Try opening the problematic pdf in
Adobe Reader on your Linux box and it renders it just fine. The same
should be true on Windows.
That config file solves the problem for all uses of R on my Linux box,
and as this configuration file is in my home folder it is local to me
and doesn't require root permissions which may be a problem if the
machine you are running this on is not 'owned' by you.
That way you wouldn't have to remember to set the use of dingbats and
can benefit from the improved rendering dingbats provides.
